The Seongsan Ilchulbong Peak looks as if its the top of Poseidon’s head, for this majestic attraction’s features resemble that of a crown, while some say that it resembles a gigantic ancient castle. A volcanic eruption which is said to have occurred 100,000 years ago, caused the Seongsan Ilchulbong Peak to rose from under the sea. The peak has a gigantic crater on its top, which is about 600m in diameter and 90m in height. But what completes the diadem-like look of this peak is the 99 rocks surrounding the crater, therefore making it look like a crown. And according to Wikipedia, the Seongsan Ilchulbong Peak displays diverse inner structures resulting from the sea cliff. These features are considered to be of geologic worth, providing information on eruptive and depositional processes of hydromagmatic volcanoes worldwide as well as past volcanic activity of Seongsan Ilchulbong itself.
Located on the eastern end of Jeju-do Island, the southeast and north sides of the island are cliffs, the northwest side is a verdant grassy hill that is connected to the Seongsan Village.
The ridge is a surreal spot for nice walks and for horse riding as well.
The sunrise is said to be 10x more beautiful while at the peak, and the Seongsan Ilchulbong Peak is also praised for the surrounding bright yellow colored canola flowers in the spring, making the site extra ravishing.
